§ 97.205 Repeater station.
(a) Any amateur station licensed to a holder of a Technician, General,
Advanced or Amateur Extra Class operator license may be a repeater. A
holder of a Technician, General, Advanced or Amateur Extra Class
operator license may be the control operator of a repeater, subject to
the privileges of the class of operator license held.
(b) A repeater may receive and retransmit only on the 10 m and shorter
wavelength frequency bands except the 28.0-29.5 MHz, 50.0-51.0 MHz,
144.0-144.5 MHz, 145.5-146.0 MHz, 222.00-222.15 MHz, 431.0-433.0 Mhz,
and 435.0-438.0 Mhz segments.
(c) Where the transmissions of a repeater cause harmful interference to
another repeater, the two station licensees are equally and fully
responsible for resolving the interference unless the operation of one
station is recommended by a frequency coordinator and the operation of
the other station is not. In that case, the licensee of the
non-coordinated repeater has primary responsibility to resolve the
(d) A repeater may be automatically controlled.
(e) Ancillary functions of a repeater that are available to users on
the input channel are not considered remotely controlled functions of
the station. Limiting the use of a repeater to only certain user
stations is permissible.
(g) The control operator of a repeater that retransmits inadvertently
communications that violate the rules in this part is not accountable
for the violative communications.
(h) The provisions of this paragraph do not apply to repeaters that
transmit on the 1.2 cm or shorter wavelength bands. Before establishing
a repeater within 16 km (10 miles) of the Arecibo Observatory or before
changing the transmitting frequency, transmitter power, antenna height
or directivity of an existing repeater, the station licensee must give
written notification thereof to the Interference Office, Arecibo
Observatory, HC3 Box 53995, Arecibo, Puerto Rico 00612, in writing or
electronically, of the technical parameters of the proposal. Licensees
who choose to transmit information electronically should e-mail to:
(1) The notification shall state the geographical coordinates of the
antenna (NAD-83 datum), antenna height above mean sea level (AMSL),
antenna center of radiation above ground level (AGL), antenna
directivity and gain, proposed frequency and FCC Rule Part, type of
emission, effective radiated power, and whether the proposed use is
itinerant. Licensees may wish to consult interference guidelines
provided by Cornell University.
(2) If an objection to the proposed operation is received by the FCC
from the Arecibo Observatory, Arecibo, Puerto Rico, within 20 days from
the date of notification, the FCC will consider all aspects of the
problem and take whatever action is deemed appropriate. The licensee
will be required to make reasonable efforts in order to resolve or
mitigate any potential interference problem with the Arecibo
